.SPECIFICATION forming part of Letters Patent No. 745,404, datedDecember 1, 1903.

liipplicatinn filed August 8, 1903.

To all whom it may concern:

Be it known that I, DANIEL W. TOWER, a citizen of the United States,residing at Grand Rapids, in thek county of Kent and State ofIlIichigan,-hare invented a new and useful Device for FasteningFurniture-Trimmings, of which the following is a specification.

This invention relates to certain improve ments in devices for securinghandles, pulls,

io knobs,and similartrimmin'gs tofurniture and the like, and has for itsprincipal object to provide a securing device that will securely held aknob or other trimming-in place, vpreventing turning or loosening of theknob or l5 pull under all conditions of use.

A further object of the invention is to provide a securing device thatwill in part embed itself in the wood and prevent turning of thesecnring-screw,and,further,to apply thesame zo construction to a knob orhandle, so that neither the knob nor the screw can be turned and theknob held permanently in place.

A still further object of the invention is to provide a knob-securingdevice of simple and z5 economic construction in which the securingmember proper may be formed of steel, iron, or other cheap metal andconcealed by an ornamental hood or washer of ornamental character.

Vith these and other objects in view the invention consists in the novelconstruction and arrangement of parts hereinafter described,illustratedin the accompanying drawings, and particularly pointed out in the ap- 55pended claims, it being understood-that various changes in the form,proportions, size,

and minor details of the structure may be made Without departing from.the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings, Figure 1 is a sectional elevation of adrawer-knob or the like provided with a fastening means in accordancewith the invention. Fig. 2 is a detail perspective View of the knob.Fig. 3 is a similar view of the knob-locking washer and the ornamentalwasher that conceals it.

Fig. 4l is a similar view of the headed portion of the screw andthescrew-locking washer.

5o Fig. 5 is a sectional viewillustrating the application oftheinvention to an ordinary form of drawer-pull. Figs. 6 and 7 are viewsof Serial No. 168,8().3- (No model.) l

slightlymodified constructions of washer. Figs. 8 and 9 are similarviews of slight modiiications of the screw-heads.

Similar numerals of reference are employed to indicate correspondingparts throughout Athe several figures of the drawings.

In drawer pulls and knobs'of ordinary construction it is usual to employa securing- 6o screw extending through the front portion of the drawerfrom the rear surface toward the front and engaging a shank formed onthe knob or pull, and in other cases to employ small eyebolts extendingthrough the drawerfront and provided at their inner ends with ordinarynuts, the eyes receiving the'ends of handles or pull members. Suchfastenings are quickly loosened from constant use and areasourcecfannoyance in using the cheaper 7 a class of furniture.

In carrying out the present invention provision is made for firmlylocking the parts, so that it will be im possible for the screw tobecome loosened or the knob to turn from ordinary use.

.In the drawings, l represents the front of a drawer or similarstructure provided with a transverse opening 2. Through this openingextends a securing-screw 3, the head 4 of the 8o l screw being disposedat the rear surface of the drawer-front. The base of the screwhead isflanged, as indicatedat 5, and on its under surface are formed a numberof projections or corrugations alternating with 8 5 notches, asindicated at 7. The corrugations may be of any number and of anysuitable shape, as shown in Figs. 4, 8, and 9. 0n the inner end of thescrew .is placed a washer 8, having inturned prongs or spurs 9 of anyde- 9o sired number which embed themselves in the woodwork when thescrew is driven home, and the upper or outer face of said washer isprovided with corrugations and notches, as indicated at 9', in order toengage the corre- 95 spending notches andcorrugations onthe inner faceof the screw-head, and thus prevent the screw from turning. Thescrewenters the rearwardly-extended portion of arknob l0 or stud ll ofthe drawer-pull, and in the roo latter case the stud is prevented.v fromturning by the pull-handle yl2, as shown in Fig.

5, so that it will be unnecessary to employ any auxiliary means forpreventing turning of the stud, and when once the screw is tightlyturned the studs or prongs will embed themselves in the wood, while theinterlocking of the notches and corrugations formed in the adjacentfaces of the screw and washer will prevent the screw from working loose.

Vhen used in connection with a knob, it becomes necessary to providesome means for preventing turning of theknob under careless handling,and for this purpose the inner end of the knob is provided with a boss13, that is non-circular in form, and while in the present instance itis shown with two diametrically-opposed flattened sidesllc it is to beunderstood that the shape may be triangular, rectangular, or any formthat is not circular. This boss tits within an opening formed in awasher 15, the washer being dished and its peripheral flange having aplurality of studs or prongs 16, that enter the wood at the front of thedrawer. The receiving-opening for the boss is formed by a suitable die,and the side walls of the opening are turned inward to form flanges 17,preferably of a depth about equal to that of the periphery flange 15, sothat they may come into contact with the front of the drawer, and thusprevent crushing of the washer while the screw is being tightened and atthe same time by binding against the front of the drawer aid the studs16 in preventing turning movement of both the Washer and the knob. Thiswasher is formed of steel, iron, or other cheap metal, and in order toconceal the same I employ a second cover or washer 18, formed of lightbrass or other suitable metal and held in place bya flange at the rearend of the knob. This finished washer is also provided with an openingcorresponding -in shape to the boss 13, and is therefore held fromturning, so that noneof the parts can work loose and the knob cannotbecome accidentally detached.

Having thus described the invention, what is claimed is- 1. In asecuring device for furniture-ttings, a revoluble threaded memberprovided on its inner face with projections',and a dished washer havingcorresponding projections on its outer face, the inner face of saidwasher being provided with a plurality of wood-engaging spurs at itsflanged margin, the spurs serving by engagement with the wood to preventturning movement of the washer in either direction.

2. The combination with a knob having a non-circular boss, of a dishedwasher having peripheral wood-engaging spurs, anda bossreceiving openingat the center of the washer, one or more of the walls of said openingbeing turned inward to strengthen the washer, and means for securing theknob in position.

3. In combination, a knob having a noncircular boss, a dished washerhaving a eentral boss-receiving opening the walls of which are turnedinward for a dist-ance corresponding to the depth of the Washer,integral spurs or prongs at the periphery of said Washer, and means forsecuring the knob in position.

4. In combination, `a knob having a non-circular boss, a reinforcedwasher having abossreceiving opening and provided with edge spurs orprongs, a linished disk covering the locking-washerand held in place bythe knob, and means for securing the knob in position.

5. In combination, a knob having a noncircular boss, a locking-washerhaving a noncircular opening the Walls of which are turned inward toreinforce the washer, peripheral spurs or prongs on said washer, awasher of finished metal held in place against the lock-v ing-washer atthe rear portion of the knob, a screw adapted to a threaded opening inthe knob and provided with a corrugated head, and a dished washer havingcorrugations interlocking with those of the head, the flanged peripheralportions of lsaid dished washer having a plurality of projectingwood-engaging spurs.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature inV the presence of two witnesses.

DANIEL W. TOVER.
